Copernicus and The Earth is Not the Center of the Universe

Okay, this might be a recurring idea in my blog entries. I was thinking about Copernicus. You remember him? He was a priest and an astronomer from the 14 and 1500's. He was the guy who came up with the Heliocentric Theory. In other words, the idea that we as the Earth are NOT the center of the galaxy, rather, the big bright hot thing (the Sun) was the center. He made this hypothesis after research and observation. It was not so much a guess, as much as a really smart guy doing actual scientific research to come to this conclusion. Nowadays, we might all have a good laugh at the fact that this theory was ever challenged (much like that crazy "Round Earth Theory"), but back when Copernicus made this claim, there was a firestorm of controversy from EVERYONE, but especially the church. The church at the time (of which he was a minister, let's not forget) interpreted the scriptures and the role of mankind-based on their perception of the Bible-as being central to everything (including the universe). So, of course, this heliocentric theory was heresy. To be sure, any one of us would have had some difficulty swallowing that we weren't the center of the universe, based on what our experience as mankind had been up until then. What I mean is, you can't REALLY blame people for getting pissed off, ya know? But hindsight is always 20/20, unless of course you're talking about politics inthe 21st century thus far. But I digress.
Oh, and by the way, before all of the really well learned scientists and historians (you'd be surpised folks)...(well, not really) who read my blog go crazy, I realize that it was actually Galileo who took the brunt of the religious condemnation for this theory (and others). He did step it up the next level, but the fact remains that Copernicus popularized and exposed heliocenricity. Plus, for the sake of my point I don't want to juggle two names and centuries, so there!
Anyway, my point. My point is that Copernicus's theory really rocked the boat, needless to say. He was called a heretic despite being a christian (as was Galileo). And it was a serious paradigm shift for everyone, and especially for the church. To the church of the day, they could not reconcile this theory (despite it's logical and scientific merit) with their faith. It was a crisis of faith no doubt, and would have been a serious stumbling block.
Fast forward 500 years and some change. We KNOW the earth is not the center of this solar system. We know it's not the center of this galaxy. We know there are millions of galaxies in the universe. And we know there is no end in sight yet of the universe. Just like we know that the earth is round. All of us in the christian community have learned to accept that. It might have taken a few years, but are all on the same page there. And we're still christians. We have been able to reconcile our faith with those scientific facts. A person who does not believe in the heliocentric theory would be considered a caveman by all, even Falwell.
Here's my question:
Since there's always more things to discover, both spiritually and scientifically. Since I believe that God will continue to give us wisdom and enlightenment through his spirit, just as I believe we will continue to study further into space and our own planet. And since I don't believe that all the great discoveries of our history have ALREADY been made, then here's my question:
What IS or WILL BE our next Copernicus situation? As a human race AND as a church.
Is there something (a theory or an idea) going on right now that we as the church are fighting tooth and nail as being heresy or a damage to our faith? And 300 years from now, will christians then look at us and be like "Cavemen, man. How could you NOT believe that?"
For the sake of an example, lets take the literal 6 days of creation. There is some very good science, logic, and biblical evidence to support the fact that the 6 days of creation are, in fact, NOT literal days. That they are hyperbole, or metaphor, or what have you. Maybe some day I'll do a post just about that. Mind you, I'm not saying God didn't create the universe, I'm discussing the manor in which He did. But for an example, take it. You have Christian who will think you're not saved if you don't believe the literal days, or you're not strong in your faith, or stupid, and so on. They will spout facts that they got on "answers.org" or something, they will try to use the bible to prove it, they will say things like "but the bible says it, and this and that." All those things may be true and passionate (if nothing else), but it doesn't change the fact that there is good strong evidence the other way (discovered by people who are very smart and went to good schools, and in some cases don't have anything at stake in their research).
This post is not an advocation of any view (I have my ideas, but another day), but is a question being posed. The idea of the 6 literal days is ONLY one example of many. But the question is: Is there a modern day heliocentric theory? Is there something that we could be wrong about? Something that we feel is so vital to our faith and salvation that we will fight against anyone or anything (including reason and logic, and sometimes our own consciences) in order to keep it at bay? Something that 100 years from now, our great grandchildren will look back and say "Wow, I can't believe they believed that." Kinda like how we look at the Church during the days of Copernicus and Galileo... But they (our great grandchildren) could still be believers. And still love and trust Jesus. Still be Christians.
Just a thought.
